BUNDLING, BINDING, AND 'IYING MACHINE.

To all whom it may concern:

Be it known that I, OHA s E. EVANS,

a citizen of the United States, and resident of Seattle, countyof King; State of Wash ington, have invented certain new and useful Improvements in Bundling, Binding,

'and Tying Machines, of which the, following is a specification.

This'invention relatesto improvements in the binding and tying machine described in my co-pending application Serial No. 9,311,

filed February 19, 1915.

The objects of the invention are to pro-- vide a machine which is entirely automatlc in its operation-to make one complete cycle of movements after it is started; to provide a yieldableand adjustable means for compressing the bundle prior to being bound with a wire;'to provide a tension means for vthe wlre; to provide a tension means for the wire which is entirely independent of the means for compressing the bundle; to provide an arrangement of parts whereby the knot in the wire will be tied at a corner and making equal angles with the adjacent surfaces ofthe bundle; to provide means for tucking down the knot against one of the ;surfaces of the bundle; to provide a novel means for releasing the clutch which controls the twister driving mechanism; to provide a novel means for moving one of the twister-parts toward and from the other;

to .provide' power means for actuating the bundle support; to provide a machine of the type mentioned in which all of the operative parts are above the floor and accessible; to provide novel and automatic means for moving the bundle support outward after the compressor has acted; and generally to improve this type of machine. Other objects willbe apparent from the description taken in connection with the drawings, in which,-

As clearly shown in Figs. 1 and 2, the machine comprises a base 20 having an upstanding post 21. At the top this post carries a bracket 22 securely fastened thereto in any suitable manner, and intermediate of its ends has slidingly mounted thereon another bracket 23. This latter bracket has rigidly secured thereto a horizontally arranged frame which may consist of two spaced apart and oppositely arranged chan- I Specification of Letters Eatent. t t d 1m 9, 1 1 Application filed Octoliel' s, 1916.. Serial No. 123,567. 2

which cooperat with the rldges 31 on the ways-25 to securely hold the bundle support in contact with the ways. At the opposite end of the bars 29 similar pieces 32 are secured. This bundle support is. adapted to carry a bundle A from the position of the support shown in Fig. 1 inward to position the bundle in the location shown in said figure. Power means is provided to move the support in both directions, and consists of a cylinder 33 which may be secured tofone I of the channel bars 24: and has the usual view taken onthe piston and piston rod 34, the latter being connected to a depending lug 35secured to rod 38 controls the valves in both of the valve chests, and is adapted to be actuated manually in one direction by a lever 39 and to'be operated in the opposite direction by a spring 40 interposed between the valve chest 37 and the connection 41 of the lever 39 to the valve rod. The valve rod carries a collar or block 42 which is located, as

shown in Figs. 1 and 2, and has a notch 43 formed on its upper side. This notch is adapted to cotiperate with the end of a lever 44 pivotally mounted intermediate of its ends on the valve chest 36. A bar 45 is pivotally mounted between the channel bars 24 and projects outside of one of the channel 'bars to carryan arm' 46 which is operatively connected with the lever 44 by means of a link 47. This bar 45 carries an arm 48 10 cated between the channels 24, for a-purpos presently to be described.

A compressor is carried by the machine in position to coiiperate with the bundle to compress the same after it has been placed in operative position in the machine. In

the embodiment herein disclosed this compressor 49 is mounted on a plate 50 carried by the channels 24 at the lower flanges thereof. The plate 50 is hung from these flanges by means of bolts 51 and is spaced from the same by means of thimbles 52 arranged around the bolts. The compressor 49 has a plunger 53 which carries a platform 54 at its upper end, adapted to contact with one side of the bundle. This plat; form 54 is formed with a groove 55 for the wire which encircles the bundle. The slidable bracket 23 and all the parts carried thereby are counterbalanced by a weight 56 which is hung from a chain 57 passing over wheels 58 being attached to the said bracket at 59. The'wheel 58 is arranged to be operated through a Worm wheel 60 which in turn may be actuated by a hand wheel 61.

The worm and worm wheel provide means for also looking the bracket 23 in any adjusted position because the wormwheel can not drive the worm.

The bracket 22 at the upper end of the post has rigidly secured thereto another bracket 62 which carries the twisting mechanism. This twisting mechanism has been fully described in my said prior application Serial No. 9,311, and as the specific details of the twister form no part of the present invention it will be described only in a general way. The twister consists of two separable parts, each of which is mounted ina corresponding bearing block. One ofthe twisted parts is mounted in a half bearing block63- and the other in a complemental block-64., The bearing block63 is carried by a verticalbar 65 and is mounted to'be moved toward and from the bearing block 64. In order to properly register the two blocks when they are together, one of the blocks 63 carries side plates 66, each having a projecting tongue 67 adapted to be received in a groove 68. At its upper end the twister carries a split gear 69 which is operated by a spur gear 70 non-'rotatively tively connected to a shaft 79 which is driven by a motor 80 by means of gears 81,

'82. The clutch members 77, 78 which may be of any. desired type, are urged toward. each other by a spring 83. The clutch mem-- ber 78 is adapted to be moved away] from the clutch member 77 against the tension of the spring 83 by means of a clutch yoke 84 rigidly connected with a rock shaft 85. This rock shaft carries a long bent arm 86 which, at its, upper end, is operatively connected with a longitudinally movable bar 87 arranged over the face of the bevel gear. 75. The spring 83 of the-clutch normally tends to move this bar 87 downward across the face, of said gear. Means is provided, however, for holding the said bar 87 in its'upward position so as to compress the spring 83 and d'isengage'thecluftch members. This means consists of a plate 88' (see Fig. 6.) attached to the end of the bar 87 and formed with a notch 89 adapted to catch against the side of a guide 90. A spring 91 tends to hold said bar 87 with the notch 89 in cooperation with the guide 90. Means which will be presently described is provided for moving the bar 87 laterally to trip the same and permit the spring 83 to engage the clutch member. The mechanism for thus tripping the bar 87 is carried by the movable bearing-iblock 63 and is clearly illus- .trated in Fig. 6. A bracket or bar 92 is attached to the fixed bearingblock 64 and carries the beforenientioned guide 90 at its outer end. This guide is rectangular in shape, as shown in Fig. 6, and furnishes a bearing for both the lateral and longitudi nalmovement ofthe bar 87. Adjacent this guide 90 the bar 92 is formed with a lug 93 aving an adjustable set screw 94' at its outer end; Said bar 92 is also formed with two spaced apart upstanding cars 95 between which is 'pivotally mounted thedog J which is adapted to cotiperate with the bar I 87 to push the'bar laterally and free the notch'89 from. the guide 90.' All of the above described .parts' are carried by the stationary bearing member.. The movable thereby compress the spring 104. The spring 109 acting against the latch 107 will force 4 -1,sa4,2se

bearing member 63 carries at its upper end a bracket 98' having two guide wheels 99 and 100 for the wire mounted therein. This bracket has a laterally extending. bearing :101 for a vertically movable plunger bar 102.

This bar is formed with a collar 103 at its lower end and-a spring 104 is interposed between said collar and the bearing .101. At its upper end this .plunger is formedwith an enlarged head 105 which carries a laterally projecting pin 106 adapted to cooperate with the long arm of tlie dog 96,. The bearing 101 carries a bent lever or latch 107 which has one arm adapted to catch under the head 105 to hold the'plunger in position with the spring 104 compressed. The other arm of this bent lever is arranged substantially horizontally and is adapted to cooperate with the set screw 94. In the downward movementof the movable bearing block the end of the plunger 102 strikes against the set screw 108 (see Fig.1) to the vertical arm thereof under the head 105 to hold the plunger in its extended upward position. When the said bearing block almost reaches the upward limit of'its motion the horizontal arm of the latch 107 will strike the set screw '94, thereby tripping the latch and permitting the spring 104 to move the plunger downward. In this downward movement the pin'106 will strike the long arm of the dog 96 turning the same so that the short arm 97 thereof will push the bar 87 laterally, thereby tripping the same.

' The beforementioned bar 65 is;guided for yertical movement in the bearings 110 and 111 and carries on one side thereof a rack 112. Acylinder 113-is arranged horizontally on the base 20 and has operative con-1 nections with thesaid rack 112, whereby the I movable bearing of the twister may be reciprocated in a verticaldirection. The cylinder 113 is'adapted tobe secured to said base in any preferred manner and carries at each end thereof valve chests 114 and 115. A valve rod 116, extends into each of these chests and is adapted to actuate the valve contained therein. A piston rod-117 extends into the cylinder and isadapted to slide in and out of the same. This piston rod is operatively connected to a .rack bar. 118

which is arranged in parallel relation to the-piston rod and is adapted'to reciprocate in ways'oarried on the under side of the cylinder. This rack 118 meshes with a pinion 119 arranged on a horizontal shaft 120 V which carries a gear 121 in mesh with the rack 112. It will thus be apparent thatias the piston rod 117 is reciprocated the bar carrying part of the twister mechanism will also be reciprocated.

The compressor for I thebundle which has been previously describedis controlled by a valve 122 which may be secured to the side of the cylinder 113, as shown in Figs. 3 and 4. This valve has a flexible connection 123 to the compressor and exhaust outlet 124 is formed with two hooks 127 and 128 which are adapted to cooperate with a pin 129 carried by the two spaced apart bars 130 operatively connected to the valve rod 131 of the valve 122. A bracket 132 is attached to the base -20 and carries two spaced apart pins 133 arranged in the path of movement of the arm 126 and thus acting as stops to limit the movement of the same. In the operation of this valve 122 it will be noted that movement of the rack 118 rotates the shaft 120. This rotation will be frictionally communicated to the arin 126 to revolve the same until it strikes one of the pins 133. However, before the arm thus strikes one of the stop pins, one of the hooks 127 or 128 will have engaged the pin 129 and moved thevalve rod 131 to'operate the valve 122 and thus control the action of the c'ompres-' sor for the bundle. By this arrangement it will be observed that the compressor is actuated just after the movable twister head has started upward and that it is exhausted to release the bundle just after the said twister I head has started downward after the twist has been put inthe ends of the wire.

Mechanism is provided for automatically contrblling the operation of the cylinder- 113'. A rod 134 is arranged vertically and parallel to the'post 21 in bearings 135 and upper end an arm-138 which is adapted to cooperate with a notch-139 formed in a lever 1401 This lever is actuated by a spring 141' to normally) force the notch 139 down over the arm 138. Thus when the plate 30 on the bundle carrier strikes and "rotates the arm 137 thereby turning the rod 134, the arm 138 will-be rotated from the position illustrated in Fig. 2, into the position illustrated in Fig.

1 and caught in the-notch 139 of the-lever 140, thereby securing theirod 134 in its new position. Adjacent the cylinder 113 the rod 134 carries another arm 142 which is connected to the valve rod 116 of the said cylinder. A spring 143 acts'on said arm 142 .to

turn the same in such a direction as to keep,

the arm and rod 134 in the position illustrated in Fig. 2. The arrangement of-parts is such that when the rod 134 is rotated from the position of Fig.- 2 to the position of Fig,

1, the valve-rod116 will be moved to actuate.

the-valves 114, 115 sothat fluid under pressure will be admitted to the cylinder 113 'to the twister.

operate the piston rod 117 to draw the same inward, together with the rack 118, thereby rotating the gears 119 and 121 in such a direction as to elevate the movable part of When the twister has nearly completed its operation, a lug 144 on the underside of the gear 70 will strike the lever 140, thereby depressing the long arm of the same to ralse the notch 139 out of engagement with the arm 138, thereby permitting the spring 143 to rotate the rod 134 and re turn the parts to the position shown in Fig. 2. This operation of the! rod 134 will actuate the valves 114, 115, to return the movable twister head to'its-lower position, as shown in Fig. 2.

The bracket 22 carries two spaced apart laterally extending arms 145. Each of'the arms has rigidly secured thereto a side plate 146 which plates are arranged. horizontally and adapted to act as abutments against which the upper side of the bundle is pressed by the compressor. The knot tucking mechanism is carried by these two plates 146. As clearly shown in Figs. 7, 8 and 9, a block 147 having a cylindrical upper surface is secured between the two plates 146 by means of the screws 148. A curved plate 149 is.ro-

'tatively mounted on the block 147 and has its opposite edges seated in grooves 150 formed in the plates 146'. The plate 149 is formed with four lugs one located at each corner thereof. Two lugs 151 carry upwardly extending pins 152 to which are 'connected springs 153 which tend to rotate the plate in such a direction that the lugs 151 will abut the bar 154. The two lugs 155arranged opposite to the lugs 151 are adapted to be engaged by mechanism to rotate the plate 149 on the block 147. When thus r0 tated the edge 156 of the plate will engage the twisted portion of the knot and bend it down against the vertical front face of the bundle so that the knot will assume a position'such as shown-in Fig. 10. The movable twister head 63 carries at eachside thereof a' plate 157 which has pivotally mounted at its front end a bent lever 158. Onearm 159 of each of these levers is arranged substantially vertically and has its upper end formed with a hook 160 which is adapted to cotiperate, with a lug 155 on the plate 149.

The other arm 161 of the lever is arranged substantially horizontal and has a spring 162 connected therewith and acting to tendv V to rotate the lever in a clockwise direction as viewed in Fig. 7. A pin 1 63 limits the movement of'thearm 161 so that said arm cannot move above asubstantially horizontal position. In view of this description it will be apparent that as the movable twister head moves downward the hooks 160 will. on gage the lugs 155 thereby pulling around the plate. 149 so that the edge 156 thereof will tuck down the knot. After the plate 149 ieaaaae has rotated far enough to so tuck the knot corner of the bundle and the twisted portion thereof makes equal angles with the top and front 'faces of the bundle, that 1s, the twisted portion is arranged at substantlally 45 with respect to the top horizontal surface of the bundle. Because of this arrangement both of the wires are twisted equally and are bent the same amount. Thus the two wires of the twisted portion are stressed equally in contradistinction to wires'which are twisted to form some other angle with the faces of thebundle. For instance, if the twisted portion is horizontally arranged with respect to the top surface of the bundle, that is, if the top wire continues in a horizontal direction in the twisted portion, it will be obvious that the vertical wire has a bend where it begins tobe twisted and consequently is stretched that much more.

The wire which is used to biznd the bundle extends from a source of supply 1 located where desired to a tension device which may be secured to the floor under the machine, andthence upwardly to the guide rollers 99 and 100. The tension device is shown in Figs. 1 and 2 and comprises a hollow bar or pipe 164 which extends through a hole 165 in the floor 166 and carries at its upper end two spaced apart fiat plates 167. A. series'of three rollers 168, 169, and 170, are mounted on axes secured in the said fiat plates. The

axes of the top and bottom rollers 168, 170,

are parallel and vertically in line. The axis of the intermediate roller 169, however, is arranged at one side vertically of the other two rollers so that a bend is produced in the wire as it passes over these rollers. Furthermore, this central roller-169 hasits axis mounted for adjustmentlaterally whereby the extent of the bent portion of the wire may be varied, At its lower'end the bar 164" has secured thereto a collar 171 and just below and in contact with the floor is a loosely mounted collar 172 and intermediate these two collars is a third and loosely mounted collar 173. A spring 174 is interposed between the collars 172 and 17 3 and a stronger spring 175 is interposed between the collars 173 and 171; Thus it will be apparent that when the .wire is drawn upward that because of the bend produced therein by the rollers 168, 169 and 170, the entiretension device will tend to belifted 'upward hnd that this upward tendency will is placed on the bundle support when the,

- latter is in the position shown'in Fig. 1.

The operator then grasps the lever 39 and pushes it to the right, thereby compressing the spring 40 and moving the block 42 to the right so that the lever 44 catches in the notch 43 therein to hold the valve rod 38in the positionindicated in Fig. 2. This move-, ment of the valve rod manipulates the valves to admitfluid pressure so that'the piston rod 34 will be drawn into the cylin-' der thereby moving the bundle support to the right as viewed in Fig. 1. As the said; support nears the end of its inward move ment, the plate strikes the arm 137, there-. by rotating the vertical rod 134 and moving' the arm 138'at thetop thereof so that it is caught in the notch 139 of the lever 140. This rotation of the rod'134/ actuates the arm 142 to move M bottom cylinder v113 to manipulate the valves;

' to admit fluid pressure to actuate the piston rod 117 and rack l18.so that the said parts are moved'to the right as viewed in Fig. 2.

This right hand movement will rotate the gears 11?) and 121m a direction to actuate the rack 112 and connected bar 65 in an up-X ward direction to move the movable twister part toward the stationary half thereof. The rotation of the shaft 120 turns the arm 126 to thereby catch the hook 128 on the I pin129' to actuate the valve122 to admit fluid under pressure to the compressor cyl-v inder. It will be observed that, this valve 122 is actuated after the shaft 120 has made a fraction ofa rotation, that is, this valve is moved so thatthe compressor will compress the bundle just after the movable twister part has started on its upward movement.

Before the bundle moves inward the binding wire extends from the twister downward across the pathof' hebundle tothe tension device. Consequently when the bundle moves inward it pushes the wire ahead of it and thereby arrangesthe same on substantially the three sides thereof. When the movable portionof the twister head with the wire guide rollers 99 .and 100 moves upward it carries with it the wire and thus arranges the same on the front or remaining sideof the bundle. The movable twister head in its upward movement strikes the arm 48, thereby tripping the lever 44? out of the notch 43 of the block 42 and permitting the spring 40t0 return the valve rod .38 to its original position. This will manipulate the valves of the cylinder 33 so that the pis vton rod 34, together with the bundle sup-- port'will be carried to. the left' as viewed n Fig. 1 to its original position and. ready to receive another bundle.

The movable twister part continues on its upward movement and when it has almost completed the same the, arm 107' will strike the set. screw the valve rod 116- of the '94 thereby tripping the plunger 102 and actuatmg' the dog 96 to move the bar 87 later- 'ally and allow the spring. 83 to engage the clutch members 77 and 78. 7 Thus the rotation of clutch member 78 will be communicated to clutch member 77 and through the gearing to the twister mechanism-.1

When the gear 70 has nearly completed its rotation the lug 144 will strikethe lever 140 and trip the other end of said lever from the arm 138, thereby freeing the rod 134. "The gear when it has nearly completed its rotation will also carry the 1ug 17 6 against the adjustable collar 177 on the bar, 87 to move said bar longitudinally to its original position against the tension of spring 83 and to separate the clutch members 7-7 and 7 8, thus stopping the operation of the twister mechanism. '134 is free,- the spring 143 will act on the arm 142 to return said rod to its original position and also to actuate valve rod 116 .to draw the piston 117' inward and thereby ac tuate the movable twister partQto carry it downward to its low position. Shortly after After the arm 138 at the top of rod the beginning of this downward movement,

the hooks 160 'on the'said twister part will engage the tucking mechanism'to manipu- I the bundle.

I have'found that the cylinders and cooperating mechanism may be pneumatically actuated very efficiently but of course said cylinders are adapted to be used in connection with any fluid pressure. While I have shown the preferred embodiment of my 111- vention-it is obvious-that many changes may be made therein without departing from the spirit of my invention. I

While a twister comprising two separable parts is illustrated, it"iso'bvious that the organization of the machine herein dis closed is independent of the particular type of twister used, the only requirement being that some movable means be provided to take thewire downward in .front and across the path of the bundle and then upward in .rear of the same. Hence the term twister part is used to refer to any part of the mechanism which may move downward and upward across the path of the bundle support. R
